Connective tissue proper

Question 1

What are the two subcategories of connective tissue proper?

Answer 1

loose connective tissue and dense connective tissue

Question 2

Types of loose connective tissue

Answer 2

Areolar, adipose and reticular

Question 3

Why is loose connective tissue loose

Answer 3

Because extracellular matrix is organized into loose strands and cells
(areolar is Latin for a “little open space”)

Question 4

Why is dense connective tissue dense

Answer 4

Less ground substance, densely packed collaged

Question 5

Types of dense connective tissue

Answer 5

Regular, irregular, elastic

Question 6

Function of areolar

Answer 6

provides support and helps to protect organs, muscles, and many other tissues

Question 7

Where is areolar tissue located?

Answer 7

Underneath the epidermis of the skin

Question 8

What is the function of adipose

Answer 8

Warmth, stores energy, absorbs shock and slows heat loss

Question 9

Where is adipose located?

Answer 9

Under the skin of the sides, butt, breasts, kidneys

Question 10

What is the difference between regular and irregular dense connective tissue structure?

Answer 10

fibers in regular are arranged parallel whilst fibers in irregular are not

Question 11

What is the difference between regular and irregular dense connective tissue function?

Answer 11

Dense regular connective tissue is found in ligaments and tendons. Dense irregular connective tissue is present in the dermis of the skin.

Question 12

Dense fibrous (regular) function

Answer 12

provides firm attachment, pulls muscles, stabilizes bones

Question 13

Location of Dense regular

Answer 13

Between skeletal muscles and skeleton (tendons and ligaments)

Question 14

Dense fibrous (irregular) function

Answer 14

Strength to resist forces from different directions, prevents overexpansion of organs

Question 15

Location of Dense irregular

Answer 15

Visceral organs, nerve and muscle sheaths, dermis

Question 16

Function of reticular connective tissue

Answer 16

Filters, engulfs, destroys

Question 17

Function of reticular fibers

Answer 17

forms a scaffold for other organs

Question 18

Location of reticular tissue

Answer 18

Bone marrow (makes blood), spleen (filters old blood cells), lymph nodes

Question 19

Why do lymph nodes swell when you’re sick?

Answer 19

Because they are filtering out the bacteria

Question 20

Why do dense connective tissues heal so slowly?

Answer 20

Because they are avascular

Question 21

What fibers and cells are in areolar tissue?

Answer 21

Elastic fibers, collagen fibers, fibroblasts, microphages, fat cells, plasma cells

Question 22

Fibroblasts

Answer 22

Make fiber

Question 23

Microphages

Answer 23

are large cells that are capable of moving about and ingesting foreign substances, including microorganisms in the connective tissue.

Question 24

What cells and fibers are in dense regular

Answer 24

Collagen fibers and fibroblasts

Question 25

What cells and fibers are in dense regular

Answer 25

Collagen fibers, fibroblasts, elastic fibers

Question 26

General function of loose connective tissue

Answer 26

consists of relatively few protein fibers that form a lacy network, with numerous spaces filled with ground substance and fluid.

Question 27

Mast cells

Answer 27

cells that release chemicals, such as histamine, that promote inflammation.

Question 28

three major components of extracellular matrix

Answer 28

protein fibers, ground substance, fluid

Question 29

Elastic fibers

Answer 29

have the ability to return to their original shape after being stretched or compressed, giving tissue an elastic quality.
